摘要
描述了合肥光源储存环满能量注入系统的物理设计,包括设计目标、局部凸轨物理参数选择和系统性能模拟.解析分析和数值模拟结果表明,新设计注入系统具有非常高的注入效率,配合合肥自由电子激光实验装置中直线加速器改造,注入效率接近100%;同时,储存束流扰动很小,质心发射度增长满足束流稳定性要求,系统具有向准恒流运行模式发展的潜力.
The physical design of full energy injection system in Hefei light source （HLS） was described, including design goal, choice of main parameters of local bump and numerical simulation of system performance. Results from analytical derivation and numerical simulation demonstrate that, the injection efficiency under new system is very high which is nearly 100%, and perturbation on stored beam is small, whose centre mass growth is lower than orbit stability requirement. As a whole, new injection system possesses the potential to develop top-up operation mode.
